" the city and countyot Philadelphia, State of adapted to fill an open-mouthed bag" or box with material, to fold down and seal the top or month of the bag, to dry thepackage, and to feed it out of the machine.

My present invention consists. of certain improvements in machines of the character described and. claimed. in -my Patent No, 449,225, dated March 31,1891. 1.. My p'r t invention pertains to the mechnmsm f r receiving and fliling the bags, and for closing, transporting and delivering the packages, and has for its object to improve the parts of the machine performing. these functions so as to secure sbetter handling of the packages during the various operations performed upon them. 7 The mnchi'neiillustrated in my said patent includesgenerslly three mechanisms; of which the first weighs out the material to be packaged into charges of uniform weights; the second mechanism constitutes a bag machinewhich takes sheets or paper from s pile, npplies peste to. them, folds-them into a. tube around a. for|ner,'closes and sealsthe bottom, and feeds the completed bag'thus made off from the former; while the third mechanism is'essehtislly a packaging machine which receives the completed bag from the bag-mak- I ing mechanism fills it with the weighed out charges of material, shakes down or compacts the material, folds down and seals the month or top of the bag to make a. closed package, dries the package, and finnlly delivers it out of the machine. 1

Referringto th'e'drawings, let A designate in-general the frame of the machine, B astationary horizontal table which is shown as ofannular -form concentric with a vertical shaft expanded or contracted, preferably in 'the' manner shown in Fig. 8, by formingthe rear side E of the pocket as a movable back wall, it being formed with a cross-bar 0 having parallel rods 6 e extending on opposite sides of the pocket and sliding in holes formed in hearing lugs c c. \Vhen the movable back or side E is pushed in, the pins c project out in front of-the pocket, and mechanismis provided to press against these pins to expand the pocket, as will be presently described. A driving mechanism is provided for intermittently rotating the shaft (3 and pocket-carryingwhcel l),th e extent of rotativemovement being equal to the distance 'from one pocket tothc next.

shows the 'plunger'moving down.

senses I will now describe the operation in general. Assuming first that a paper bag has been formed around a vertical former G (Fig.

1) by means'ofthe bag forming mechanism (not shown), this'bag havingaclosed'bottom,

-the bag is first removed from its position around the former, as shown at a in Fig. (2,

#and carried do'wn' into one of the pockets E standing directly beneath the former. This operation is accomplished by two verticallyrnoving plungers-G' and I (Figs. 6, 7 and 36).

The plunger-'1 ascends from its normal position in the opening B in the table B, rising through the pocket E until it presses against the bottom of the bag, while the plunger G which rests at the bottom of the hollow former G holds the bag against the plu'nger'l", and both plun'gers'then move down together until the bag is carried into the pocket E, where .upon t'he' plunger G'- ascends to above the level of the bag, as shown in Fig. 7. Fig. 36

The pluner G" is mounted on a verticallymoving slide Gr moved up and down by a-lever (i (Fig. "36) which is driven by a cam, G (Fig. 36) as shown in my'said patent. The plunger-I is mounted on a vertical slide 1, connected by slink to alever'l which is vibrated by a cam 'I',(Fig. 36) to move the plunger up and down,as shown in my said patent. The empty baghaving thus been carried into the poe'ketgtheseries of pockets executes a partial rotationg whereby this pocket is moved forward onespace, or from the position E in Fig. 2 to the position-E. Y At the next movement-the pocket is carried to the position E, where it stands underneath a feed spent 0' leading down from the weighing apparatus hereinbefore referred to, or from any other source of supply of the material who filled into the packages.- The pocket is shown in this position in Figs. 9 and .10. The pocket here stands over'two holes or slots .0 0 (Figs. 3-and 6) in the table B. The supply of the material ishere dumped down through the chute G into thebag; If by chance a-bag should have been omitted, or its bottom should not have been properly. sealed, the mate -ial thus introduced will fall through the slots 0 c and be carried away.- At the next intermittent movement ofthe pockets, the pocket in question reaches the position E in Fig. 2, the pocket being shown in this position-in Figs..l1 and 18. Here the bag is repeatedly lifted and dropped in order to shakedown and compact its contents. The bagstands overopeningst' ouby the teeth of awheel or cam T fixed on several successive movements of the pockets,

heated drying table N, shown best in Fig.- 14, consisting of a hollow segmental ring extended over the path of travel of the pockets, and filled with steam, by which the bags areheated and their pasted seams dried. Steam enters this chamber through 9. pi pe N and the steam or water of condensation leaves it through a pipe N The package is thus dried during until finally the pocket whose operation we are following passes out from under this drying chamberand reaches a positionover the opening IS in the table B, which position is shown at E in Fig. 2. The bag here rests on a plate or plunger which stands in the opening B (Fig. 3). This plunger, which is operated from a cam and intervening mechanism, asshown in Fig. 29, there upon rises,lifting the package out of th pocket and to slightly above thetop thereof, 0 the position shown in Fig. 15. Thereupon a pushing plate R behind the package executes a for-' ward movement and slidesthe package onto the table Q, and onto an endless traveling belt Q, by which the package is carried out of the machine.

The operations and the mechanism thus far described do not difler substan tially from those of the machine described in my said.

patent. I will now proceed to describe the improvements therein introduced by my present invention.

The purpose of making the pockets adj ustable by means of the slidingback E is to ento grip the bag or package, and expandedto release it. In my said previous patent, each pocket in its entire revolution from the point where it receivesthe bag to the point. where the package is expelled trout it, is contracted and expanded only once. This contraction occurs in the position where the top of the bag is closed in,- and it is re-expandod while the completed package is being expelled from it, in order that by its expansion it shall be in readiness to receive a new bag when it reaches" ,ing them to project beyond the front or outer side of the pocket. as shown in Fig. 6, and I provides moving part to act against those protruding ends to press them back and thereby to throw back the movable wall of the pocket to expand the pocket. This moving part is shown as a disk in Fig. 16 at J', mounted on the slide J 5 or asa moving part J in; Fig. 17

mounted on a slide J these slides being movable in proper timeto cause the part J. or J 3 to push in the protrudingends of the pins 2', and

' thereby push back the rear wall E of the of. the pocket, instead of by mechanism en-' pocket. This wall is thereby acted upon to expand the pocket wholly from. the exterior By my prcstering the pocket and acting directly against the inner side of the back wall,as in my former patent. v

"With the construction shown in my former patent, difficulty would be apt to be enconntered by reason of the adherence of the bagto the upper plunger G, which might occur through the exudation of the paste from the bottom folds of the bag, so that after the bag was carried down properly into the pocket, the return or upward movement of the plunger G might lift orcarry the bag back more or lose out of the pocket. To overcome this dimculty my present invention provides for the contracting of the pocketimmedlately'upon the plunging of the bag down into it, this contraction being sulficient to cause the pocket to firmly grasp the bag and hold it during the upward movemeumof the plunger G. accomplish this I provide an arm K, preterably carrying a roller at its end. and arranged within the annular table B and back of the openingB, it's-position being shown in Figs. 2 and 3. This arm K is nmunted on an oscillatory shaft K having anarm Kconnected by a. link K to a lever K pivoted at K and acted on by a cam 7:, on the shaft 20, 1

as shown in Fig. 27. After the plnngers have carried the bag down to the bottom of the pocket, this cam causes the lever K to move toward the pocket, so. that this roller acts upon the rear projection e (Figs. 7 and 8) and pushes the back E of the pocket so as to contract the pocket and grip the bag. The pocket remains thus contracted or collapsed until the position E is reached, and until after the charge of materialhas been dumped into the bag, whereupon the-pocket is expanded in order to release its grasp upon the filled bag, so that upon reaching the position E the bag may befreely lifted and dropped within the pocket. By delaying the rec:- pending of the pocket u'n-til this time, the advantage is gained that the pocket is con tracted and embraces the bagat the time when the charge of material is being introduced into the bag from the chute C, so that the bag is firmly supported while the material is thus dropped into it, and is conse: quently not bulged outwardly orstrainedj'uy. the pressure of the material as it is thus rap] idly or forcibly introduced into the bag. This is especially important when the bag is freshly made and the paste uniting its seams has not yet dried or set. .Infsueh case,-it' tl ie.

open its scams.

, The means as to partly oted to an arm 1' of a three-arm lever Lwhich for expaudingthe pocket to re-- lease the bag before shaking it down is shown so that itmay be freely lifted and dropped. .When the pocket reaches the position Win misses the position 13 over the openings 0 c, and af tier the baglias been filled the disk or pusher J" moves toward it, encounters the protruding ends ofits pins e, and pushing them in pushes back the movable back section E, thereby ex-- pandin g the pocket and releasing the package which the top of the bag is folded down, it comes opposite a lever arm M (Figs. 3 and 28). As soon as the plunger U after having descended has moved up to its normal position again the lever M commences to move toward the pockct, and its end, which is preferably provided with a roller, engages a projection e on the rear of the movable back .E of the pocket and forces it in so as to. contract the pocket and compress. the package, holding ittirmly therein during the operations of folding down the top. The-importance of having the package tightly held during the completion of the closing and pasting down of its top will be readily understood. The arm M is actuated bya. cam M (Fig. 26) which vibrates a lever M pivoted at- M and acting through alink M on a short arm M connected with the lever-arm M. i This mechanism is somewhat different from that shown in Fig. 42 of my said .previons pate'nt. cording to'niy previons construction no means is provided for graduatingthe extent to which the pocket should be closed upon the package.

Inasmuch as it is occasionally necessary to vary the size 'of the package in order to 9.0- cornmodatc it to material which is more or less bulky in relation to its weight, or for other reasons, it is highly desirable. that the operator shall be able to regulate at willfthe extengto which the pocket is-contracted upon the package. To this end i interposeascrew adjustment m (Fig. 2 6) the screw being so ar-' ranged as to bewithin reach of the attendant for adjustment. In the construction shown the screw m is interposed so as to vary the point of connection between the lever Mand the link M. 'lh'eleverM" is jointed to ii-sliding block movable longitudinally of the link and constituting anut engaged by the screw m, which is rotatively pivoted in a bearing carried by the end of the link and engaging the screw in such manner that it cnnnot'move longitudinally relatively to the link. After the pocket has been closed upon the package,

its movable back retains its position frictionally after the advance of the pocket beyond the lever M, andcontinnes to hold the packagean'd maintain it in proper shape during the dry'ng operation. In my former patent the poo et after being contracted'upon the package during the closing of the'top thereof, was not again expanded until the package was being lifted ontjof the pocket. When the plunger 0 started to lift the package out,

the pocket was'stilleontraeted upon the peekthe pocket; acted to expand it. The iiexpansion of the pocket consequently did not serve to facilitate the operation of delivering out the package, but merely served to prepare the'pocket for receivingthe next empty bag that should-be plunged down into it. Ac-

cording to my present invention I provide for ex pend-in g the pocket before the operation of expelling the completed package is commenced, in order that the package may be lifted out freely and without its expulsion being resisted by the frictional cling of the pocket. This expanding of the pocket is performed by the pusher J shown in Figs. 3 and 17. This pusheris mounted on a slide J moving beneath the table B and guided by a plate or guideway b". The slide is connected by a link'H to an arm I of. the oscillatory lever I before referred .to', which isdriven as hereinafter explained; This lever l executes its oscillation in a direction to draw inthe pushers J and J 8 against the pockets shortly after the intermittent forward movement of the pockets, so that afterthe pockets have come to rest in their new positions they areexpanded by t'he pnshers J? and J. Th s ex:

pension of the pocket occurs before the plnnger Ocommences to ascend in order tolrft out the package. In my former pat'e'nt,the package having been lifted above the top of the pocket by thelplnnger, was pushed off by a reciprocating slide. In my present com Rmounted on an arm R and having a vibratory motion around a stud r on which this" arm is pivoted (Figs. 2 and'l5) the arm being vibrated by a cam B (Fig. 35) on the shaft 20 acting on a 'leverR? which is conn ect'ed' through a link with the lever-arm R. 'ihe; pushing plate R consequently has a sweeping motion which thrusts the package in the are,

of a circle, turning it partly around and directing it properly onto the delivery belt Q. Subsequently-the, plunger'O descends before the next advance of thelpockets'.

My present invention provides an improved means forimparting the intermittent for carrying the pockets, and a more positive' motion for advancing them and for locking The them fast during their periods of rest. pockets are fastened to'the exterior of a ring or wheel 1'), shown detached in Fig. 5, the run of whichis connected by spokes to'a central;

and the other arm F of which is connected by a link Ff to the bolt.- Upon this same shaft is also secured another cam f (Fig. 3) which acts upon one arm of the beil-cran k-le; ver F I pivoted at F and connected by a link FF, shown in dotted lines in Fig. 3, to the lever B, so as to vibrate this lever st intervols the distance from one bolt-hole or notch d to the next. The actionofthese parts can he readilyifoliowedz'ihe bolt F is first protruded so as to enter a notch d, after which by the action of the cam f the lever F is swung forward so that the bolt carries with it the wheel D and the series of pockets the distance from one pocket to the next; subsequently the bolt is drawn back to clear the notches d, and the lever F is returned to its starting point, after which the bolt F is agniu protruded and after the-proper interval of time the operation is repeated. The bolt after pushing forward the wheel I) comes to a stop and'thereby stops the wheel and pockets before the bolt is retracted, to disengage it from the notch d, thereby insuring the stoppage of the pockets in the correct position.

In the drawings, I have shown the device for opening the pockets as actuated also from the cam )1 and through the bell-orhnk-lever F F A link 11 jointed to the arm F'of this lever connects to the oscillating lever I before described, having the arms I and I which are connected by links to the slides of the pushers J and :7 before described. As before stated, the .pocketsj'are expanded immediately after the forward movement of the pockets, and as soon as they have come to rest, andthis is verygconveniently performed at the some time that the bolt F" is operated to retract it from the notch,so that the bolt andpocket-expanding pushers are verysimpl y operated from the same cam. f

-I have found that it is highly'importaut to provide a device that will act with certainty and precision to hold the several pockets in their proper positions during the. several operations-and especially during the closing of the top of thgmckage. r this purpose I provide it etc pin, catch or clutch which will engage and hold the pockets or their carrying wheel during the time when the bolt F is retracted and disengaged from the wheel.

Bucha device is shown in Figs. 2, 21 and 25.

-1t consists in the construction shown of two arms or fingers S, preferably carrying rollers on their ends, adapted to grip the pocket at opposite sides, and moved n or out at proper times by means of a cam S (Fig.25) acting .on an'arm S of a lever S which carries the arms S. The shape of the cam is such as to throw the. arms into engagement with the pocket when the bolt F is retracted, and to hold the arms in engagement therewith un-' til'the folding of the top of the package is completed and the bolt has again engaged the carrying wheel D ready for another forward feed, at which instant the arms S are drawn back to let the pocket move freelypast.

In the construction shown the machine is driven by power applied to the shaft 15 through fast and loose pulleys U U. This shaft carries worms U meshing with worm wheels-l l on two vertical shafts 16 and 17. The shaft 16 carries the cams V -W and m for operating the bag-closing mechanism. The shaft 17 carries the cams Z and in of the 'bag closing mechanism, and the cams f f of the mechanism for advancing the pockets. A horizontal shaft 18 is driven by bevel-gears from the shaft 16 and carries the cum 0 for working the plunger 0. A horizontal shaft 19 is driven by bevel-gearing from the shaft 17, and in turn drives another horizontal shaft 20. The shaft 19 carries the cams M for working the pocket-0' ening arm M, the toothed wheel or cam 'l for working the shaker, and the cam U, for working the plunger U. The shaft- 20%carries the cam k? for operating the pocket'opening arm K.

It must not be inferred from the detailed description which I have given of the preferred construction of my machine that my invention is necessarily limited to the exact details of construction shown.

Many of the features-of my'machine are susceptible of considerable modification in structural respects without departing from the essential features of my invention. For example, the described construction of the pocket to enable it to be expanded and contracted is not essential, as any construction of pocket which will admitof being contracted to grip the bag and expanded to release it might be substituted. v

The mechanism for expanding and contractiug the pockets might be considerably varied, it being only essential tethese mechanisms that they shall engage the pockets in such manner as to cause them to expand or contract to the requisite extent and at the proper times. In the case of a pocket constructed with the movable back or wall E, this wall might beotherwise'nionnted than by the rods e, or if such a mounting be employed a single rodmight suffice in place of the two rods shown, although the construction illustrated is preferred.

A -a means for centering and holding the pockets in proper position dnringiheir peri:

ods of rest, some other mechanism than the ing the pockets in position being admissible .that shall correctly center the. pockets or bring them into proper register with the operfating mechanism.

As the agitating device for shaking down the contents of the bag forms no part 0! my present invention, it might be substituted by any-other mechanism for agitating or shaking down the. contents.
